Multiple Buck controller, single panel

[hamdi.tn]

Hi everyone,

Kind of stupid question i think, but as the title said, am planning to use a single panel to power-up multiple smps (as current source) for LEDs.
I can't think about anything that make paralleling multiple buck controller possible using a single solar panel,as long as there is enough power.
am i wrong ? will all the switching introduce unexpected behavior ?

Thanks.
